What does βjournalctl -b -1 -e | lessβ say when you run it after a crash? Like the last 20 lines.
Also when it crashes can you get to a different tty by pressing ctrl-alt-F2 or is the system completely locked?
I will try these out and report back
Here's what I got from that command. Everything below the "Shutting down" command. Lookint through what it provided... there is a LOT in that search that I don't understand. It looks like it recorded it from last night (when I had not experienced the issue) instead of just now.

π sorry if I grabbed too much
The command needs to be run after you crash. It's showing the logs of the last time you boot (That's the "-b -1") which is why you're seeing yesterday's log.
I don't see anything crazy in this output.
You can change the options to trawl the logs if you like. type in "man journalctl" and you'll get a man page entry explaining what each of the options and how to use them.
Well, it's not a hard crash. I lose functionality on my taskbar, and can't run any programs π
Can't even shut down π
When it happens can you swap to a different tty by pressing CTRL-ALT-F2 after things stop responding? If you get a terminal with a login screen then that means your desktop environment is hanging, not your computer.
Nothing happens. I thought i might have had the wrong hotkeys and had to double check
Then I would check the ram to make sure it's ok. Download memtest86+ load it on a thumbdrive and boot from that. Then run the memtests. It will tell you if your memory modules are fucked or not.
The tests may take some time to run so go grab a beer while you wait.
Memtest just finished. Everything is fine
My next test would be trying to a live installation in order to see if it's hardware related or software.
Boot into a live cd (I would use one that is the same distro as you already have) and do what you normally do. See if the machine locks up. If it doesn't then you've probably got some broken setting or program crashing your machine. If it does crash then some other hardware is causing the issue. You'd have to start taking out each piece of hardware out of the system to see if your crash is still there or not.
Haha, yup! Been running them for 2 hours already π
